Vehicle mounting system

ABSTRACT

A system for mounting an object within a vehicle. The system has a housing, a pair of rotatable objects at least partially received within a respective opposed end of the housing, a pair of locking elements within the housing and movable between a locked position in which they exert a locking force against a respective rotatable object, and an unlocked position in which the locking element does not exert the locking force against the respective rotatable object. A handle extends from the housing and is coupled to the locking elements through a rigid linkage within the housing. The handle is pivotable between an extended position in which the handle moves the pair of locking elements via the rigid linkage to the unlocked position and a locked position in which the handle moves the pair of locking elements via the rigid linkage to the locked position.

This application is a continuation of U.S. patent application Ser. No.17/146,543, filed on Jan. 12, 2021, the contents of which areincorporated herein by reference in their entirety.

FIELD OF THE INVENTION

The present invention relates generally to mounting systems, and moreparticularly, to systems for repositionably mounting objects within amoving vehicle.

BACKGROUND OF THE INVENTION

Specialized vehicles are an essential tool in many differentprofessions. For example, professions such as law enforcement commonlyutilize a number of specialized electronic systems (e.g., computers,radio systems, sirens) that are not found in conventional automobiles.Other professions and enterprises also commonly have a need to usevehicles with similar specialized equipment. For example, customizedelectronics systems are frequently installed in vehicles such asforklifts, waste collection trucks, utility trucks, constructionequipment and agricultural equipment. While vehicles may be speciallymanufactured that include these systems, these systems may also be addedto conventional automobiles or other vehicles through after-marketinstallations. However, one problem that arises from such installationsis the simple and effective mounting of after-market electronic devicesin conventional vehicles. Improved systems are desired forrepositionably mounting objects in vehicles.

DETAILED DESCRIPTION OF THE INVENTION

The systems disclosed herein are usable to provide mounting for objectswithin conventional vehicles (such as automobiles). While the disclosedsystems are described herein with respect to mounting within the cabinof a vehicle, it will be understood that the invention is not solimited. To the contrary, aspects of the present invention are usable inany application in which a repositionable mount is desired.

While any objects may be mounted within the disclosed systems, thedisclosed mounting systems are particularly suitable for mountingelectronic devices, such as laptops, tablets, or mobile phones. Suchdevices may be subject to periodic use within the vehicle, and as such,the disclosed systems advantageously allow such objects be repositionedbetween a “use” and “stow” position while remaining mounted to a portionof the vehicle. Other electronic devices or objects mountable with thedisclosed systems will be known to those of ordinary skill in the artfrom the description herein.

With reference to the drawings, FIG. 1 illustrates an exemplary system100 for mounting an object within a vehicle in accordance with aspectsof the present invention. System 100 is usable to repositionably mountobjects, such that they can be moved within various stable positionswithin a vehicle. In general, system 100 includes a housing 110, a pairof rotatable objects 130, a pair of locking elements 150, and a handle170. Additional details of system 100 are provided herein.

Housing 110 houses the components of system 100. Housing 110 has a pairof opposed ends 112 on either side of an elongated body. The elongatedshape of housing 110 provides distance between the mounting surface andthe object to be mounted. When installed, one end 112 of housing 110 ispositioned adjacent the mounting surface, and the other end 112 ofhousing 110 is positioned adjacent the object being mounted.

In an exemplary embodiment, housing 110 has a hollow tubular shape, andmay include features such as ribs to enhance rigidity and ergonomicshapes or grips to enhance ease of use. For example, as shown in FIG. 1, the side of the housing opposite the handle 170 may be arched toreduce the overall size and help users grasp the housing 110. As shownin FIG. 2 , the housing 110 comprises a pair of hemicylindrical housingshells 114 which are mated to one another to form housing 110. Housingshells 114 may be mated to one another, for example, by screws, bolts,adhesives, ultrasonic welding, friction fitting and so on. In anexemplary embodiment, one of the housing shells 114 includes a pluralityof screws 116 for attaching to the other housing shell 114, as shown inFIG. 2 . One or both of the housing shells 114 may include one or moreopenings, such as corresponding cutouts 140, for accommodating handle170.

Each end 112 of housing 110 includes a partially spherical surface 118therein. A portion of each partially spherical surface 118 is formed byeach housing shell 114, such that when housing 110 is assembled, thepartially spherical surfaces 118 provide a partially spherical concavespace within housing 110. Each rotatable object 130 is dimensioned tofit inside each partially spherical concave space, with a portion of therotatable object 130 extending outside housing 110 via a respectiveopening defined at its outer perimeter by a respective perimeter wall120. Each rotatable object 130 and perimeter wall 120 is dimensioned toallow the rotatable object 130 to move relative to housing 110throughout a range of travel, such as shown by the arrows in FIG. 1 .

In an exemplary embodiment, each rotatable object 130 has a sphericalportion 132, which is referred to herein as a ball. Each rotatableobject 130 has a mating structure that is configured to be attached toeither the mounting surface of the vehicle or the object to be mounted.Non-limiting examples of mating structures include threaded rods orscrews, apertures to receive bolts, pins or rivets, keyed projectionssized to mate with corresponding apertures on the mounting surface ormounted object, and so on. The mating structure also may be internal tothe ball portion 132 of rotatable object 130. For example, the mountingstructure may be formed as openings in rotatable objects 130, into whicha corresponding projection on either the mating surface or mountedobject can be inserted. It will also be understood that system 100 mayinclude one or more additional components (not shown) for attaching themating structures to either the mounting surface or the mounted object.

In the shown example, the mating structure comprises a base 134 havingscrew holes or the like, and a stem 136 connecting the base 134 to theball portion 132 of the rotatable object 130. Stem 136 is dimensioned tofit within perimeter wall 120 with room to move in one or moredirections to provide the desired range of motion.

Handle 170 extends from housing 110 and may be rotationally coupled tohousing 110 by a handle pivot 172. As used herein the term “pivot”includes any rotational connection, such as a pin that fits into a bore,and the location of a pivot is defined by the axis of rotation providedby the rotational connection. Handle pivot 172 may comprise, forexample, a pin 172 a extending from one or both housing shells 114 toextend into a correspondingly-sized bore 172 b through handle 170.

Handle 170 is movable relative to housing 110 between an unlockedposition (see, e.g., FIGS. 4A and 5A) and a locked position (see, e.g.,FIGS. 1, 4B and 5B). In the unlocked position, handle 170 may protrudefrom housing 110, and in the locked position handle 170 may lie along orbe flush with housing 110, such as shown in FIG. 1 . However, neither ofthese configurations is strictly necessary in all embodiments.

System 100 also includes a pair of locking elements 150 positionedwithin housing 110. Each locking element 150 is movable within housing110 between a locked position in which the locking element 150 exerts alocking force against a respective rotatable object 130 to resistrotation of the rotatable object 130 relative to the housing 110, and anunlocked position in which the locking element 150 does not exert thelocking force (or exerts less force) against the respective rotatableobject 130, thus freeing the rotatable object 130 is to rotate relativeto housing 110.

Movement of the locking elements 150 is controlled by handle 170 by wayof a rigid linkage 180, an example of which is shown in more detail inFIGS. 3A and 3B. Exemplary rigid linkage 180 includes a drive link 182and a pair of driven links 184. Drive link 182 is coupled to handle 170,and driven links 184 are coupled between drive link 182 and respectiveones of the locking elements 150. For example, in the shown embodiment,drive link 182 is coupled at a first end 182 a to handle 170 by a firstpivot 186, and extends to a second end 182 b where it is coupled to thedriven links 184 at respective second pivots 188. Second pivots 188 areshown in the example as being spaced from each other (i.e., theirrespective pivot axes are not collinear), but other embodiments may havecollinear second pivots 188, and such collinear second pivots 188 mayshare a common pivot pin, bore, or other features.

Each driven link 184 extends from a respective first end 184 a at therespective second pivot 188, to a respective second end 184 b where itis coupled to the respective locking element 150 by a respective thirdpivot 190. Each of the first, second and third pivots 186, 188, 190 maybe constructed using any suitable rotating connection. In the shownexample, each pivot is formed by a C-shaped receptacle 192 into which apin 194 is snap-fit. This allows simple and rapid assembly andservicing. In other cases, pins, screws, or other mechanisms may be usedto rotationally secure the parts. The pivots 186, 188, 190 also may beformed by flexible webs of material (i.e., so-called living hinges), inwhich case one or more of handle 170, drive link 182 and driven links184 may be integrally formed (e.g., injection molded as a singlecontinuous part).

Operation of system 100 is illustrated in FIGS. 4A and 5A, which showthe system 100 in an unlocked position, and FIGS. 4B and 5B, which showsystem 100 in a locked position. In the unlocked position, handle 170 isoriented about handle pivot 172 to protrude from housing 110. Some orall of drive link 182 may protrude from housing 110 in this position,but this is not required in all examples. In this position, drive link182 and driven links 184 are positioned with second pivots 188 offset byrespective first distances D1 on one side of a drive axis 196 (i.e., animaginary straight line) extending between the third pivots 190.

Starting from the unlocked position, handle 170 can be rotated abouthandle pivot 172 towards housing 110. During such rotation, handle 170moves drive link 182 and second pivots 188 towards drive axis 196. Assecond pivots 188 move towards drive axis 196, driven links 184 causelocking elements 150 to slide away from each other along drive axis 196.Locking elements 150 eventually move far enough to press againstrotatable objects 130 with sufficient force to hold rotatable objects130 in place against normal service loads. At this point, second pivots188 are spaced from drive axis 196 by a second distance D2 that is lessthan first distance D1, and the system 100 has reached a lockedposition.

Optionally, but not necessarily, the rigid linkage 180 may be configuredto move into a self-retaining locked position, such as shown in FIG. 4B.Specifically, one or both second pivots 188 may move far enough to passacross to an opposite side of drive axis 196 by a third distance D3, atwhich point further movement is prevented by a travel stop (e.g.,contact between handle 170 and housing 110). Third distance D3 is lessthan or equal to second distance D2. Thus, locking elements 150 arepositioned along drive axis 196 where they clamp the rotatable objects130 against movement. To remove rigid linkage 180 from theself-retaining locked position, it is necessary to move second pivots188 across drive axis 196, which requires a slight movement of lockingelements 150 away from each other. Thus, absent any external force beingapplied to lever 170, the lever 170 and rigid linkage 180 will remain inthe self-retaining locked position.

When it is desired to unlock the rotatable objects 130, handle 170 ismoved back to the unlocked position. This movement pulls drive link 182,and thus second pivots 188, away from drive axis 196, which causesdriven links 184 to pull locking elements 150 towards each other. Whenthe parts have reached the unlocked position, locking elements 150 arepositioned to permit adjustment of the positions of rotatable objects130. In this state, locking elements 150 may be completely out ofcontact with rotatable objects 130, but more preferably are in lightcontact to provide a force sufficient to hold the rotatable objects 130against movement until a user applies an external force to makeadjustments. The selection of suitable forces for locking and unlockingrotatable objects 130 will be understood by one of skill in the art fromthe description herein.

Rigid linkage 180 preferably does not include elements that are intendedto significantly deform during use, such as mechanical or pneumaticsprings or the like. Thus, except for slight deformation of the partsthat might (but does not necessarily) occur during the transition to andfrom a self-retaining over-center position, movement of handle 170 leadsto a proportional change in position of the components of rigid linkage180 regardless of loading. However, locking elements 150 and/orrotatable objects 130 may include elastic features, such as overmoldedelastomeric layers or the like. Examples of such features are discussedbelow.

Referring to FIG. 6 , each locking element 150 may comprise a sleeve 152having a partially spherical locking surface 154. Sleeves 152 aredimensioned to slide within corresponding bores formed in the hollowhousing 110, and are movable along drive axis 196 between the locked andunlocked positions. To this end, each sleeve 152 may comprise a profilehaving an outer wall that extends parallel to drive axis 196, and theouter wall may be shaped with a non-circular profile to counteract anyrotational torques that might be applied by contact with rotatableobjects 130. For example, the shown sleeves 152 have a six-sidedrectilinear perimeter profile that matches a corresponding six-sidedrectilinear bores 152′ (FIG. 2 ) formed within housing 110.

Each partially spherical locking surface 154 faces and contacts arespective rotatable object 130. Partially spherical locking surface 154may be formed as continuous surface (e.g., a single surface having aradius of curvature about a central point), or it may be formed byplural surfaces (e.g., multiple surfaces that are not connected but areall have a radius of curvature about a common point). Partiallyspherical locking surface 154 also may be formed by a collection ofshapes that effectively form a partially spherical surface, such as anassembly of pins that terminate at points that are located equidistantlyfrom a spherical center, or an assembly of flat facets that aretangential to a common spherical center.

In a preferred embodiment, either the partially spherical lockingsurfaces 154 or outer surfaces of the rotatable objects 130 is coveredwith or has regions of a compressible material. The compressiblematerial may be a compressible rubber material, and elastomeric polymer,or other material adapted to create friction between locking element 150and rotatable object 130. The friction between these objects preventsrotation of rotatable object 130 relative to housing 110, andimmobilizes the mounted object in the desired position. Similarly, thepartially spherical surfaces 118 of housing 110 also may includecompressible friction-generating materials.

In the shown example, each rotatable object 130 is covered with acompressible material. Each partially spherical locking surface 154comprises a main surface 154 a that is curved about a single sphericalcenter point, one or more raised ribs 154 b that protrude from mainsurface 154 a towards the spherical center point, and one or moregrooves 154 c that protrude away from main surface 154 a away from thespherical center point. Ribs 154 b form a primary point of contactbetween locking element 150 and rotatable object 130, and main surface154 a may also contact rotatable object 130 upon application ofsufficient force to press ribs 154 b deeply enough into the compressiblematerial. Grooves 154 c are regions in which locking element 130 doesnot contact rotatable object 130, but the compressible material mayextrude into grooves 154 c upon application of sufficient locking force.Thus, ribs 154 b and grooves 154 c enhance the locking force againstrotatable object 130 by creating mechanical interference againstrotation.

Referring now to FIGS. 7-11 , various exemplary embodiments of rotatableobjects 130 are described. In each case, the rotatable object 130 has aball 132, base 134 and stem 136.

In FIGS. 7 and 8 , base 134 and stem 136 are formed as a unitary plasticor metal part, such as by injection molding or casting, and ball 132 isformed by an elastomeric material that is overmolded onto the preformedbase 134 and stem 136. In FIG. 7 , stem 136 includes a single cross post137 that extends perpendicular to stem 136, and in FIG. 8 , stem 136includes two cross posts 137 that extend perpendicular to stem 136.Other embodiments may use other numbers or orientations of cross posts137, and one or more cross posts 137 may extend from only one side ofstem 136.

In FIGS. 9 and 10 , stem 136 includes a plate 138 that extends radiallyfrom stem 136. In these example, plate 138 is curved to form asemi-spherical surface at the top of stem 136. In other cases, plate 138may be flat, conical, or have other shapes. Plate 138 also may belocated along the length of stem 136, rather than being at the end. Stem136 also may include axial ribs 139 that extend from stem 136 tobuttress the bottom of plate 138. In these examples, ball 132 isovermolded over the preformed stem 136. In FIG. 9 , stem 136 isintegrally formed with base 134, whereas in FIG. 10 , stem 136 is formedseparately from base 134, and attached to base 134 by a fastener such asa screw.

FIG. 11 shows a rotatable object 130 having ball 132 overmolded ontostem 136 having one or more recesses 133 formed therein, such that thematerial forming ball 132 permeates the recesses 133. The exemplaryrecesses 133 comprise bores that extend axially along stem 136, butother shapes may be used.

FIGS. 12A through 13B show additional embodiments of a rotatable object130. Here, the rotatable object 130 also includes a ball 132 overmoldedonto a stem 136, and the stem 136 is selectively connectable to multipledifferent bases 134. A first base 134 a is shown in FIGS. 12A and 12B,and a second base 134 b is shown in FIGS. 13A and 13B. The end of thestem 136 opposite the ball 132 includes a first connection interface142, and each base 134 a, 134 b includes a corresponding secondconnection interface 144. The connection interfaces 142, 144 may engageeach other to hold the stem 136 at a fixed position on the base 134 a,134 b. For example, the connection interfaces 142, 144 may have matchingteeth or crenellations that engage to prevent rotation relative to eachother. Alternatively, the connection interfaces 142, 144 may includesliding surfaces to allow free relative rotation between the parts. Thestem 136 is selectively secured to either the first base 134 a or thesecond base 134 b by a fastener 153, such as a screw, which pulls theconnection interfaces 142, 144 together to form a secure fit. It ispreferred that the connection interfaces 142, 144 do not allow anyrelative movement between the base 134 a, 134 b and the stem 136 whenthe fastener 153 is fully secured, but this is not strictly required.

The geometry of the first base 134 a differs from the geometry of thesecond base 134 b in one or more ways to accommodate differentinstallation requirements or user preferences. For example, the secondbase 134 b may have a shorter height than the first base 134 a, such asshown in the illustrated example. More specifically, each base 134 a,134 b includes a respective fixation member 146 a (e.g., a mountingplate having holes for fasteners), 146 b, and a respective mounting post148 a, 148 b upon which the respective connection interface 144 ispositioned. The mounting post 148 b of the second base 134 b is shorterthan the mounting post 148 a of the first base 134 a, such that itsconnection interface 144 is located closer to the fixation member 146 b.In other cases, the bases 134 a, 134 b may be configured with therespective connection interfaces 144 at different angles relative to thefixation member 146 a, 146 b. In still other cases, the fixation members146 a, 146 b may have different geometries (e.g., a flat plate for thefirst fixation member 146 a, and a curved plate for the second fixationmember 146 b). Other alternatives and variations will be apparent topersons of ordinary skill in the art in view of the present disclosure.

The rotatable objects 130 of FIGS. 12A-13B also show a further variationof the stem geometry to secured the ball 132 to the stem 136. In thisexample, the stem 136 terminates at a cage 151 comprising an outerperipheral surface having a plurality of openings. In this case, thecage's outer peripheral surface is generally spherical, and the openingsare configured as triangular cutouts. In this case, each cutout is adistinct volumetric space that does not intersect the other cutouts, butin other cases the cutouts may intersect each other to form continuouspassages through the cage 151. The ball 132 may be overmolded onto thecage 151, such that material flows into the cage openings to provide amore secure fitment of the ball 132 to the stem 136.

Embodiments such as those shown in FIGS. 12A through 13B may be providedseparately (e.g., with only one of two bases 134 a, 134 b), of as kitshaving multiple different bases 134 a, 134 b.

In any of the foregoing embodiments, interaction between the overmoldedball 132 and protruding or recessed structures on stem 136 are expectedto enhance retention of the overmolded material. Combinations ofprotrusions and recesses also may be used, and other alternatives andvariations will be apparent to persons of ordinary skill in the art inview of the present disclosure. Furthermore, other embodiments ofrotatable objects 130 may use different constructions, such as amachined ball 132 to which a stem 136 is welded or threaded, a cast ball132 having a threaded insert installed therein to receive a bolt, or aball 132 formed by two shells with a bolt captured therebetween. In anycase, the selection of suitable materials for the parts will be readilydetermined through routine experimentation.

Although the invention is illustrated and described herein withreference to specific embodiments, the invention is not intended to belimited to the details shown. Rather, various modifications may be madein the details within the scope and range of equivalents of the claimsand without departing from the invention.

A system for mounting an object within a vehicle,the system comprising: a housing having opposed ends; a pair ofrotatable objects, each rotatable object at least partially receivedwithin a respective one of the opposed ends of the housing; a pair oflocking elements positioned within the housing, each locking elementmovable within the housing between a locked position in which thelocking element exerts a locking force against a respective rotatableobject to resist rotation of the rotatable object relative to thehousing, and an unlocked position in which the locking element does notexert the locking force against the respective rotatable object, and therotatable object is free to rotate relative to the housing; and a handleextending from the housing, the handle being coupled to the pair oflocking elements through a rigid linkage positioned at least partiallywithin the housing, the handle pivotable between an extended position inwhich the handle is distal from the housing and moves the pair oflocking elements via the rigid linkage to the unlocked position and alocked position in which the handle is proximate to the housing andmoves the pair of locking elements via the rigid linkage to the lockedposition.
 2. The system of claim 1, wherein the pair of rotatableobjects are a pair of balls, each ball having a mating structureextending therefrom, the respective mating structure of each ballconfigured to be attached to the vehicle or the object.
 3. The system ofclaim 2, wherein each ball is formed from an elastomeric materialovermolded over a portion of a stem that defines at least part of themating structure, wherein at least one cross post extends through theportion of the stem, and the elastomeric material forming the ball isovermolded over the at least one cross post and the portion of the stem.4. The system of claim 2, wherein each ball is formed from anelastomeric material overmolded over a portion of a stem that defines atleast part of the mating structure, wherein the stem comprises at leastone radially extending plate, wherein the elastomeric material formingthe ball is overmolded over the at least one plate and the portion ofthe stem.
 5. The system of claim 1, wherein each of the pair of lockingelements comprises a respective sleeve that is configured to slidewithin a corresponding bore in the housing.
 6. The system of claim 5,wherein each of the pair of locking elements comprises a partiallyspherical locking surface positioned to press against the respectiverotatable object when the locking element is in the locked position. 7.The system of claim 6, wherein at least one of the partially sphericallocking surface and a surface of the rotatable object comprises acompressible elastomeric material.
 8. The system of claim 1, wherein therigid linkage is configured such that movement of the handle from theextended position toward the locked position increases a force appliedto the pair of rotatable objects by the pair of locking elements, andmovement of the handle from the locked position toward the extendedposition decreases a force applied to the pair of rotatable objects bythe pair of locking elements.
 9. The system of claim 1, wherein thehandle is pivotally connected to the housing at a handle pivot.
 10. Thesystem of claim 1, wherein the rigid linkage is movable to aself-retaining locked position.
 11. The system of claim 1, wherein atleast one of the pair of rotatable objects comprises a ball fixed to astem, and a mating structure releasably secured to the stem.
 12. Thesystem of claim 1, wherein at least one of the pair of rotatable objectscomprises a ball configured to be secured to a plurality of differentmating structures.
